If you have used Siri to add a relationship on your iPhone 4S(http://www.imore.com/iphone-4s) you may be wondering how to go about removing it. Maybe you had someone labeled as a girlfriend or boyfriend and need to remove that relationship. While Siri can't remove relationships (yet) itself, we can walk you through how to do it manually.

When iOS adds relationships it simply remembers them via your own contact card. So we'll need to edit that.

1. First go into your Address Book and find your own contact card.
2. You'll want to tap Edit in the top right corner.

3. Now scroll down a little ways and you'll see a relationships section.
4. Simply delete whatever relationships you don't want anymore.
5. Scroll back up and click Done.

iOS should no longer remember those relationships. You can always use Siri or manually add relationships again anytime you want.

We've mentioned the original, FREE, MobileFiles application before, which lets you access MobileMe's iDisk via the iPhone. Well, now we've also got MobileFiles Pro and along with the $9.99 price tag comes a killer feature that a lot of productivity mavens have no doubt been waiting for:

EDIT! native Microsoft Excel 2003 documents just as you would on your desktop. Save the edited Excel file on your iPhone, send to your iDisk account remotely, or upload to your desktop using WiFi - all while maintaining perfect data integrity.

MobileFiles Pro is developed by QuickOffice, so this definitely makes the kind of sense that does. The only question is: when will Word and PowerPoint editing follow?
